Application filed August 15, 1924. Serial No'. 732,175.

The object of this invention is the con-V struction of a tightly sealed double lantern plate unit for use in lantern frames of polygonal constructionv adapted to .give minimum loss of light at the upright members ofthe lantern frame and permit a Alight strong simple construction of the frame itself. This is accomplished by making the individual glass plates with the side edges beveled so that the sides of neighboring series of plates are parallel to each other.

Fig. 1 is a side elevation of a lantern embodying the principles of our invention; Fig. 2 is a horizontal cross section on line 2-2 of Fig. 1; n

Fig. 3 is a perspective view of the lower edge of a pair of plates putV together with fastening means disclosed; v

Fig. 4. is a vertical cross` section through the center line of the lower part of a pair of plates. Y

In the figures 1 is a lantern,` especially y adapted tor streetor post lighting,2iis the top andi); the` base which can be ofany desired construction. The side frame members are shown at 4; and are fastened to l the top or bottom or are integral with vthe same. The plates here shown areput together in pairs comprising an outer plate 6 and an inner one 7.- Two sets of grooves orindentations 9 `which are carried into the outer faces of the plates for a slight distance and these portions of the grooves converge toward each other,` are preferably plaeedon the upper edgeof the plates, which grooves are adapted to retain clips 10 having convergent legs or jaws to engage the ortions of the grooves in the outer Jfaces of the plates for the purpose of rigidly holding the plates together. A single set of grooves 9 identical to theV grooves 9 is placed v at the center of the bottom of the plates, such plates being fastened together by a clip 10 identical to the clips 10. The 'form and construction of the grooves and clips are shown in Fig. 4.

One of the main features ofthe invention is itsadaptability to a lantern otpolygonal form the side edges of the plate being sloped to fit in the frames according to the number of sides in the polygon. The invention is here shown in connection with an octagonal about 76o, this angle having been found desirable from the point of view of appear ance and assembly. In an octagonal lantern with perpendicular sides the angle of the bevel of each plate would be one-half of oneeighth of the entire circle or 221/2", and after allowance for the slope 011:76", the angle 1s reduced tol about 21.9. For a hexagonal lantern with perpendicular sides the bevel angle will be one-half of one-sixth of the circle or 30? with a reduction proportionate to the slant of the sides. Y

lantern, in which the sides are sloped at.

The great advantage of using edges of the 'exact bevel required to bring the adjacent4 edges parallel when in'place in the i lantern is that by thismeans the essential requirements of the frame for holding the glass panels lin place is reduced to the simplestA possible means. If proper` provision be made for holding the side frame members at top and bottom it would be quite possible to hold the plates keyed in place by means of the outer members only without any webl intermediate between the plate surfaces. In practice, however, it is desirable to use a web in the side frame members because this permits a light strong construction and produces a seat for gaskets to protect the edges of the plates. y Or if it is desired the webs alone can be used for the same purpose without members. Y

The use of such webs with or without exterior side lmembers does away with the necessity of any interior fastening means,

passing through the glass.

lNe claim:

A polygonal lantern comprising a frame, forming flat inclined sides, a glass plate adapted to lie in eachpane iframe, each plate comprising twol pieces of! glass ot'` substantially identical size with all Yof their `outer edges in contact and the inside edges bevelled `which otherwise wouldinterfere with light to permit the sides of neighboring plates to :term a moistureeproof lantern, the opposite edges of the two pieces of glass being notched, said notches being extended a slight distance into the outer faces of the said pieces, the extensions of the notches being disposed in inwardly convergent relation to each other, and resilient clips having con 5 vergent legs straddling the plates and seated in the notches with the'legs countersunk in the convergent portions of said notches tolhold the plates in close contactwith each ot 1er.
